These begonias are planted in an eglomise planter that tempted me with and peeking through the foliage is a portrait by Jeffery purchased 20 years ago.
The McCarty kingfisher is a prized possession of his - and I’ve had the Grand Tour copy of Spinario since I was little (an homage to my godparents’ family collection of Grand Tour copies which were much, much larger that I was always obsessed with).

& that’s exactly what we did - I obsessively cut up strips of the panels at a smaller scale to work out what was actually possible, sketched all over our walls in pencil, took a video describing in detail what I wanted, and flew to London, leaving all in the expert hands of
The red metallic curtains - a fabric found and knew I would love - is trimmed with a Greek key tape from the garment district. If you look closely you can see a birthday gift from - two porcelain ‘hunks’ relaxing on the curtain rod - both admiring and being admired by their Tom of Finland friends.
The Victorian jeweled lantern came from a favorite store in Hudson where I have admired it for maybe 10 years and finally brought it home. It originally hung above a seance table in Lily Dale, New York
And of course every room - no matter the size - needs a garden seat.

It’s always interesting to see an artist’s process and the dots they connect - and how a small page of sketches and colors can translate to a larger composition.
Adding to this - aside from the colors being eerily similar…- I have a tile on my bedside table from Lockwood de Forest, one of Church’s friends and collaborators, that I purchased at Olana a few years back.

The paisley bedside tables came from an auction at and perfectly fit (after I had the baseboard removed on either side!)

Story by; photos by; styled by; visual editor
On our cover, designer William Cullum —a Thomas Jayne alum who recently launched his own firm—turns a classic Emery Roth studio into a jewel box of personal mythology (see: a mural stitched with alligators and evil eyes and a gold-tiled bathroom channeling Diana Ross–era Chelsea). He shares it with his partner and their cat Leopold, and not a single surface is wasted.
Inside the issue, Milan-based artist brings her bronze sorcery stateside for the first time. builds a rugged, artisan-made hideaway in California. Designer makes his Elle Decor debut inside an I.M. Pei landmark, and a new wave of private clubs proves that hospitality is having a big design moment. We also ask the important questions: Does a room have an age? What's the new frontier for natural stone? Can a dog bed be genuinely beautiful? (It can.) These are the names to know and the ideas already in motion. We see the future, and it looks very good. 🔮
